Re: SSL Certificate validity period

It's 3650 days (10 years) by default.

If it expired, you can generate new SSL cert and key with shell script shipped in iRedMail. e.g. iRedMail-0.7.3/tools/generate_ssl_keys.sh. Here's detail tutorial:

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
